VM's not communicating to each other

[Futki]

Hi all,

First sorry if this question is asked by somebody else in forum but I couldn find the answer.

Recently i have created a Proxmox server and created two RHEL VM. The problem is that i am in the same network with the VM's and i have connection with both of them (ping, ssh) but the nodes aren't communicating between eachother. I can ping the gateway from each node and have internet connection. I have no idea why this problem is ocuring.

Thanks in advance

Try to use 'tcpdump' to see what happens.
